OFF IG RAILWAY-GAB.

' To all 'wkont it may concern:

, Be it known that I, WILLARD F. YUJLLE, a citizen of the United States, residin at Seattle, in the county of King and tate of Washington, have invented new and useful Improvements in Railway-Cars, of which the following is a specification.

My present invention relates to cooling,

heating and ventilating devices for railway cars, and its object is to provide improved devices of that character, which will be simple and economical in construction and very efi'ective in operation. This object is QR of Fig. 2, the central air-pipe, how-- ever, being removed and portions of the section of the same on hne M- N floor, etc. broken away; Fig. 2 is a longitudinal, central, vertical section of such car on a plane corresponding with line U V of Fig. 1; Fig. 3 is a vertical transverse section of the same on line A-B of Fig. 2;

4 is a like section of the same on line C--D of Fig. 2; Fig. 5 'is a view in perspective of a removable floor plate and valve member for controlling air passages under the'floor; Fig. 6 is a central vertical section of the lower part of the car showin one adjustment of said floor late an valve member, (the central alr-pipe being partially raised); Fig. 7 is a vertical section of the same parts on line G-H of 6, the central air-pipe beinglowered) ig. 81s a similar section of the same parts, (the central air-pi e not shown), the floor plate and valve mom or being adjusted to another position; Fig. 9 is a plan view .of a. portlon of one ofv the floor air-conduits, etc; Fig. 10 is a vertical section of the same parts on line KL of Fig. 9; Fig. 11 is a v rtfi cal 0 1g. 9; Fig. '12 is a vertical section of such car on line,S-'T of Fig. 1; Fig.1? is a vertical section of the telescopf central air-pipe in its closed or raised position; Fig. .14 is a I horizontarsection of the same on line OP Specification'bf Letters Patent.

of F g. 13;Fig. 15 isa side view of said air-plpe in its lowered or extended position;

Fig. 16 is a vertical section of the same mcludmg a rotary fan; and Fig. 17 is a diagram of the electric connections for operatingjthe fan and heating the air currents.

' he car body 1 has, ice chests 2 at the ends and a raised floor 3 providing air pas sage underneath. A vertical air-pipe 4, preferably located near the middle of the car, is adaptedto be'lowered into its operative position shown in the drawings,.and to be raised for convenience in loading the car, etc.

This end may be effected in various ways, as by forming said pipe in telescoping sectlons 5 and by hing ng the pipe to the car ce ling as at 6, the plpe bemg' held in its raised position. by suitable means, as by the hook 7; or either construction,the telescoping sections or the hinging of the pipe to the ceiling may be ada ted to the desired end without the other. fan is employed to force air through this vertical pipe for ventilation, cooling, or heating the interior.

This fan may be of various constructions. It may comprise the double rotary fan wheels 8, the vanes of one being faced oppositely to those of the other, so that by rotating the shaft 9 (on which both fans are carr'led), inone direction, air is forced downa ward into the pipe, and in the other-direction air is drawn u ward through the same.

Or, in another mo e, the fan 10 may be 10- cated, as shown in Fig. 16, near the lower end of said pipe, being driven through the flexible electric connections 11. Suitable power, as the electric motor 12, having battery 13 and switch-board 14, is employed to drive the fan. The space between the car a floor and the car bottom is divided into a middle air passage 15 which communicates with the ice chests 2, and into side air passages 16, each extendinglengthwise of the car. Thecar floor shown is provided with raised slats 17 extending in the said direction and with an air conduit 18 formedby into theinterior of the-invertedchannel-iron 19 located over an opening member 24 is adapted to fit the floor open-- ing, so that, in one position, (shown in Fig. 8) this member resting by its oppositely disposed flanges 25 on the car bottom closes the floor opening and continues the floor at the same level. By inverting the member 24 and inserting it 1n such position that the flanges 25 are in the position shown in Figs.

6 and 7, communication with the side air-' passages 16 is cut ofi by the flanges, while communication is open between the middle air-passage 15 and the air-pipe 4, etc.; but if the member 24 is turned a quarter-way around and inserted then communication with the middle air-passage 15 is closed by the flanges, .while the way is open between the side air-passages 16 and the air-pipe 4, etc.

When it is desired to cool the car, the inverted member 24 is turned so as to open communication with the middle air-passage 15, the air-pipe 4 is lowered, its guide members 26 engaging the sides of the floor-opening 22, and the fan is driven in the direc-.

tion to draw air upwardly through the airpipe '4. This continuously circulates the air, from the top of the car through the openings 27, downwardly through the icechests 2, through the middle air-passage 15, and thence upwardly through the air-pipe 4.

If now, it is desired to heat the car, the inverted member 24 is turned so as to open communication with the side air-passages 16, the air-pipe being lowered as before, and the fan is drivenin the op osite direction, 7:. e. to force air downwardly through the air-pipe 4. This continuously circulates the air through the electrically heated grids, in-

dicated at 28, through the opening 29 into the air-pipe 4, downwardly through this airpipe into the side-passages 16, thence through the floor openings 21 into the conduits 18, thence through the openings 20 and into the interior of the car.

Mere ventilation is, of course, efiected by either of these operations, but without the use of ice or theheating grids. ,A natural circulation of air without the use of the fan, may, of course, be efl'ected through the passages and openings described, which may supplemented by the opemngs 30.

Closures 31 operated as by chains 32 through the roof-ventilating doors 33 are for the ice, drip pans 35 and water deflectors 36 are shown in the ice chests 2, and the side doors of the car are shown at 37.

Not confining myself to the details of construction shown and described, I claim:

1. In a car of the character described; a swinging air-pipe located in the freightcontaining interior of the car and pivotally supported at its upper end and adapted to be swung toward and from the floor; an air passage below the pipe; and means for de-' tachably connecting the passage and the provided for the openings 27 Supports 34 free end of the p1pe in its lowered position to provide continuous and inclosed air communication through the pipe and the passage.

' 2. In a car of the character described; a swinging air-pipe located in the freightcontaining interior of the car and pivotally supported at its upper end and adapted to be swung toward and from the floor and comprising telescoping sections; an air passage below the pipe; and means for detachably connecting the passage and the free end of the pipe in its lowered position to provide continuous and inclosed air communication through the pipe and the passage.
